The Library of Congress, through its National Library Service for the Blind and Print Disabled, is soliciting stereo headphones under solicitation number 2026-NLS-0048 for use by patrons who are unable to read printed material due to visual or physical disabilities. This is a full and open competition conducted as a single award Indefinite Delivery/Indefinite Quantity (IDIQ) contract under FAR Subpart 13.5, with a base period from September 1, 2026, to August 31, 2031, and estimated contract value ranging from $100,000 to $2 million. The headphones must meet strict technical specifications detailed in Section C and J1-Attachment, including lightweight design, on-ear cushions, an adjustable headband, a 3.5 mm stereo plug, and compliance with human engineering standards such as smooth surfaces free of sharp edges, no locking mechanisms, and no exposed electrical conductors. Proposals must include two pre-award samples meeting electrical and technical requirements but not necessarily full packaging or labeling standards, followed by twenty production control samples for approval prior to any full-scale manufacturing. A comprehensive Quality Control Plan, inspection procedures, and a Compliance and Conformance Table are mandatory, and all items must be packaged in individual 2-mil plastic bags and labeled with exact federal free matter language on cartons, with layout approvals submitted prior to production. The evaluation process follows a Best Value Tradeoff methodology, with offers evaluated across four volumes: Volume I—Samples for Pre-Award Testing (a mandatory pass/fail gate), Volume II—Technical Approach (assessing quality control, manufacturing capacity, and technical feasibility), Volume III—Past Performance (evaluating risk based on prior contract fulfillment), and Volume IV—Price (evaluated within the context of overall value). While the relative weighting of these factors is not disclosed per FAR guidelines, failure on Volume I eliminates an offeror outright. All proposals must be submitted electronically by the deadline of July 31, 2026, to the Contracting Officer and Contract Specialist, and must include current SAM registration with a valid UEI number and full compliance with required representations. The contract includes specific clauses pertaining to gratuities, System for Award Management maintenance, prohibitions on certain foreign entities and trafficking, accelerated small business payments, and warranty coverage under FAR 52.246-17. Payment will be triggered upon delivery of items or successful performance under task orders
